Definitions
- the invention relates to a gas exchange device with a Gas exchange valve and one associated with the gas exchange valve Valve stem, with an electromagnetic actuator, which in a component is mounted and an opening magnet and one Has closing magnets, between which an armature axially is arranged displaceably, the anchor via an anchor plunger together with an opening spring and one Pre-tensioned spring system on a spring Valve stem works and with a hydraulic lash adjuster, that between the armature tappet and the valve stem is arranged.
- Electromagnetic actuators for actuating gas exchange valves usually have two switching magnets, one opening magnet and a closing magnet between their pole faces an armature coaxial to a gas exchange valve axis of the gas exchange valve is slidably arranged.
- the anchor works directly or via an anchor bolt on a valve stem of the gas exchange valve.
- actuators based on the principle of the mass oscillator acts a preloaded spring mechanism, usually two prestressed compression springs, on the anchor, and an upper and a lower valve spring.
- the upper valve spring acts in Opening direction and the lower valve spring in the closing direction of the gas exchange valve.
- the closing magnet or the Opening magnet briefly overexcited or the armature caused by Oscillation routine vibrated to get this out of the To attract equilibrium.
- the armature lies on the pole face of the energized Closing magnet and is held by this.
- the closing magnet clamps the valve spring acting in the opening direction in front.
- the closing magnet switched off and the opening magnet switched on.
- the Valve spring acting in the opening direction accelerates the armature beyond the equilibrium position, so that this of the Opening magnet is attracted.
- the anchor hits the Pole surface of the opening magnet and is held by this.
- the Opening magnet switched off and the closing magnet switched on.
- the valve spring acting in the closing direction accelerates the anchor beyond the equilibrium position to the closing magnet.
- the armature is attracted by the closing magnet, hits the pole face of the closing magnet and is by this recorded.
- a game compensation element is from an older application, DE 19 647 305.5 known in which an actuator floating in a cylinder head is mounted.
- the actuator opens and closes via an anchor and two on both sides in the direction of movement the armature arranged electromagnets a gas exchange valve.
- a play compensation element between a cover plate and the actuator, that both positive and negative valve clearance balances.
- the play compensation element has a first hydraulic one Element with a lash adjuster piston in a cylinder.
- the lash adjuster is between a first, the Gas exchange valve facing away, depending on the internal combustion engine controlled and a second, facing the gas exchange valve Pressure chamber.
- There is a check valve in the piston is held in the closed position by a retaining spring.
- the Check valve opens in case of overpressure in the first pressure chamber Direction to the second pressure room.
- the retention spring is like this designed that the check valve can not open if there is no game and closes the connection between the two pressure rooms.
- the Backlash compensation element is supported on the upper cover plate, which is firmly connected to the cylinder head.
- the game compensation element can only transmit pressure forces.
- the play compensation element is only in a bore of the actuator inserted so that both parts against each other can be moved and are therefore easy to assemble. While the total time in which the closing magnet is actuated by to close the gas exchange valve, the actuator is activated by a Relief force in the direction of the gas exchange valve is relieved. Further the game compensation element is relieved as soon as the anchor is on the pole face of the opening magnet. Will that Game compensation element relieved, this expands. opens the actuator the gas exchange valve, creates an opposite Reactive force against which the game compensation element locks according to its function and yield only slowly can. It can happen that the game compensation element expands more and more and the gas exchange valve is no longer complete closes. There is a kind of inflation effect.
- this is Backlash compensation element firmly connected to the actuator and can thus absorbing tensile and compressive forces.
- the game compensation element this second variant has in addition to the first a second hydraulic element with a cylinder in which the first cylinder guided with a ring-like extension is.
- the ring-like extension also serves as a separating piston between an upper and a lower pressure chamber, the are connected via an annular throttle gap.
- the game compensation element is constructed like the one previously described Variant.
- the gas exchange valves are skewed due to space constraints Direction of the actuator installed diverging from each other. It must have a cover plate for each gas exchange valve and actuator Seals and screw set are provided.
- valve springs move the actuator when not energized Shift solenoids slowly up, causing the armature to move out of its geometric middle position between the pole faces of the switching magnets is moved.
- the one that can be subjected to tension and pressure Backlash compensation element locks the second hydraulic Element according to its function against a fast Compensation back to the middle position.
- the middle layer is under Under certain circumstances only reached after several cycles. Consequence of this is for example, an increased energy requirement and the Danger that the gas exchange valve cannot be held, because this hits the pole face of the Closing magnet hits and bounces off this or not sufficiently close to the opening magnet through the upper one Valve spring is accelerated.
- DE 33 11 250 A1 describes a device for actuation a gas exchange valve with an electromagnetic actuator known in which a game compensation element between a Anchor and a valve stem is arranged that only compressive forces can transmit.
- the game compensation element is hermetic completed and has no pressure connection through which it with Media is supplied.
- the object of the invention is a gas exchange device with a game compensation element in the manner that one in terms of friction or the constructive possibilities improved supply of the print media can be done.
- the object is achieved by the Features of claim 1 solved while advantageous refinements and developments of the invention the subclaims can be removed.
- a hydraulic lash adjuster proposed that in the longitudinal direction in a channel Anchor plunger is connected to a pressure connection.
- a feeder the print medium is sent to a suitable transfer point the anchor plunger and from this via the channel to the play compensation element.
- the game compensation element is preferably without its own Fixed guide used. This eliminates the Influences of friction of the guidance of the play compensation element, for example, by the friction dissipated energy and / or stick-slip effects between leadership and game compensation element, the deviations from the target movement of the valve.
- the game compensation element only in the area short connected to the pressure connection before and in the closed position is. Only when the gas exchange valve is closed, i.e. With its valve disc rests on a valve seat ring the length dimension, how far the game compensation element must expand so that the gas exchange valve on one side with its valve plate cleanly seals on the valve seat ring and on the other side of the anchor exactly on the pole face of the Closing magnet comes to mind.
- Actuator 2 for actuating a gas exchange valve 1, which in a recess 35 is fixedly mounted in a component 3, for example in an actuator carrier or in a cylinder head.
- the actuator 2 has an opening magnet 4 and a closing magnet 5, between which an armature 6 is axially displaceable.
- the anchor 6 is on one Anchor plunger 7 attached or made in one piece with this, with which he on a valve stem 9 of the gas exchange valve 1 acts.
- the actuator 2 has a spring system 8 below of the opening magnet 4 with a lower one, in the closing direction acting valve spring 30 and with an upper, in the opening direction Acting valve spring 31.
- the lower valve spring 30 is supported on component 3 in the direction of gas exchange valve 1 and in the direction facing away from the gas exchange valve 1 on one on the valve stem 9 attached spring plate 32.
- the upper Valve spring 31 is supported in the direction of gas exchange valve 1 a spring plate 33 attached in the armature tappet 7 and in the direction away from the gas exchange valve 1 on the opening magnet 4 from.
- the valve springs 30, 31 are preloaded to the extent that when the solenoids 4, 5 are the armature 6 in an approximately middle position between the switching magnets 4, 5 sets and immediately before the closed position of the gas exchange valve 1 a residual closing force of the lower valve spring 30 and immediately before the opening position a residual opening force the upper valve spring 31 is present.
- the game compensation element 10 is supplied with pressure oil via a cup 15, which between the play compensation element 10 and the anchor plunger 7 arranged is, with its side walls 34, the play compensation element 10 partially surrounded and externally fed in an oil pressure cylinder head fixed guide 14 is guided via sliding friction.
- the guide 14 is formed by a separate component 52 which is inserted into the recess 35 of the component 3.
- the component 52 lies with its outer circumference on the inner contour of the Recess 35 and is supported by a collar 37 in the Gas exchange valve 1 facing away from opening magnet 4 and in the direction of the gas exchange valve 1 at a stage 29 in component 3 or in the cylinder head.
- the component 52 has its outer periphery, a pressure chamber 36, over which it a channel 38 is connected to a pressure connection 13. from Pressure chamber 36 leads a channel 39 to guide 14 and opens into an annular groove 40.
- Shortly before and in the closed position of the Gas exchange valve 1 is an interior space 41 formed between the cup 15 and the game compensation element 10 via one Channel 42 in the cup 15 connected to the annular groove 40.
- the Backlash compensation element 10 is radial via a guide 44 guided.
- the anchor 6 with its anchor plunger 7, the play compensation element 10 and the gas exchange valve 1 can be rotationally symmetrical to be built in.
- Through the annular groove 40 is secure asked that the cup 15 regardless of the orientation oil is supplied during assembly.
- the pressure oil is then when required, via a recess 56 on an inner cover side 43 of the cup 15 the game compensation element 10 from above fed.
- the supply of pressure oil via cups 15 is one mature technology with few problems. However, it is also possible to use the pressure oil with or without a cup 15 directly to the side of an appropriately designed game compensation element supply.
- the game compensation element can also be guided directly in component 3.
- FIG. 2 shows an embodiment of the invention, at which a play compensation element 11 over a in the longitudinal direction extending channel 18 in an anchor plunger 16 with pressure oil is supplied or connected to the pressure port 13.
- a Guide 14 for the game compensation element 11 and in particular a cup 15 is not required. The friction on the play compensation element 11 is eliminated and the moving mass is reduced.
- the pressure oil is from the pressure port 13 via a channel 46 a ring 47 below the opening magnet 4 via a Annular groove 49 on the end facing gas exchange valve 1 fed. Within the ring 47 it becomes a second, on inner circumference of the ring 47 arranged annular groove 48 out.
- the ring 47 is supported in the direction of the gas exchange valve 1 Stage 51 in component 3 and in gas exchange valve 1 Direction facing away from the opening magnet 4, or is supported the opening magnet 4 on the ring 47, whereby the ring 47 in Longitudinal direction is positioned exactly.
- the annular groove 48 closes inwards on a guide 21 of the anchor plunger 16, which in the opening magnet 4 is used. In the area of the ring groove 48, the guide 21 has a transverse channel 45 which faces inwards to the anchor plunger 16 opens into an annular groove 20.
- the game compensation element 11 is thus shortly before and in the closed position with the pressure connection 13 connected and is supplied with pressure oil so that, if necessary, to extend to an appropriate length.
- the ring 47, the Guide 21 and the anchor plunger 16 rotationally symmetrical, independent from the alignment, which makes the Assembly is simplified. It also contributes to a simple Assembly with that the guide 21 in the longitudinal direction by a Stage 50 is fixed to the opening magnet 4, which causes the cross channel 45 in the guide 21 in the longitudinal direction during assembly can be positioned easily and precisely.
- the ring 47 can as Item to be executed; but it can also be made in one piece on Opening magnets 4 are formed and thus an integral Form part.
- the channel 18 can also be used in other areas such as in the guide 21 of the anchor plunger 16 connected to the pressure port 13 be, for example in a continuous channel 18 from the Direction of the closing magnet 5, etc.
- the guide 21 is suitable However, this is particularly good since there is an existing friction surface is used, i.e. no new ones are added and these are added Lubricated with pressure oil, which reduces friction.
- the play compensation element 11 has a cylinder 22 and a piston 24, between which a pressure chamber 26 is enclosed is.
- the pressure chamber 26 is via a throttle, not shown with an adjacent space 28, a spring space, and over a Check valve 27 connected to the channel 18.
- the game compensation element 11 is an independent, functional Unit executed, which is attached to the anchor plunger 16 is and can therefore be pre-assembled and checked beforehand.
- the game compensation element 11 is easily plugged on and still executed captively, for example by an O-ring, not shown, which engages in an annular groove etc..
- a game compensation element 12 is shown at a piston 25 is formed by part of the armature tappet 17 becomes.
- the check valve 27 is in a recess 55 inserted into the anchor plunger 17.
- the game compensation element 12 can be carried out more cheaply and easily. The moving mass is reduced. It is also possible that the valve stem 9 parts of the game compensation element 12 forms, for example by the cylinder 23 integral with the valve stem 9, i.e. the game compensation element 12 could be completely up to the check valve 27 of the Armature plunger 17 and the valve stem 9 are formed.
- the play compensation element is raised 10, 11, 12 in the first closed position of the gas exchange valve 1 to its exact length, i.e. that the anchor 6 comes to rest exactly on the pole face of the closing magnet 5 and a valve plate 53 of the gas exchange valve 1 completely on seals a valve seat ring 54.
- the game compensation element 10, 11, 12 under Compressive stress and has the tendency to shorten to always close securely by constantly throttling oil into the Spring chamber flows off. If - the game compensation element 10, 11, 12 has become too short due to the leakage back in the closed position of the gas exchange valve 1 on the exact length by the check valve 27 opens, and the Pressure chamber 26 is connected to the pressure port 13.
- the gas exchange valve 1 moves this iterative process constantly in an area of an optimal game without inflates the game compensation element 10, 11, 12.
- the gas exchange valves must always close securely. To do this achieve, have the game compensation elements on which support the gas exchange valves directly or indirectly, the Tendency to shorten slowly. This is hydraulic Game compensation elements with a corresponding Throttle point reached. If the anchor is no longer sufficient close to the closing magnet because the lash adjuster has shortened too far, a quick compensation in the opposite direction, which is with a opening check valve is reached. Such one iterative process with a fast and a slow one Compensation causes the gas exchange valve to be constantly in an area of optimal game setting.
- the play compensation element is between the anchor plunger and the Valve stem between an upper one acting in the opening direction Valve spring and a lower one acting in the closing direction Compression spring clamped. Both valve springs are preloaded so far that when the solenoids are de-energized, the armature moves in an approximately middle position between the pole faces of the switching magnets sets and simultaneously in or shortly before the closed position of the gas exchange valve has a residual closing force of lower valve spring on the play compensation element, the anchor tappet and acts on the anchor. If the anchor of that The closing magnet is attracted to and shortly before its pole face neglected the kinetic energy of the anchor, the Closing magnet the spring force of the upper one, in the opening direction acting valve spring minus the residual closing force of the Apply the lower valve spring acting in the closing direction.
- the actuator has a mass many times greater than that Gas exchange valve with its valve stem or the armature with his anchor plunger.
- the game compensation element must at Design according to the invention between the anchor plunger and the actuator only the small mass of the armature or the gas exchange valve adjust so that a slight inflating effect occurs can be compensated for by controlled leakage, without the play compensation element due to an excessive amount of leakage oil becomes too soft.
- the actuator is fixed and the game compensation element only makes the small ones Masses of the armature with its armature tappet or the gas exchange valve adjusted with its valve stem, creating energy is saved.
